Stop revising Python randomly before interviews. Jumping from one concept to another. Solving random questions without direction. Watching multiple videos and still feeling unprepared. That’s not revision. That’s panic. When interviews are close, you don’t need more content. You need structured problem solving. So I created a Last Minute Python Interview Prep video. No long explanations. No unnecessary theory. No distractions. Just: • Handpicked problems • Step-by-step thinking • Clear approach to solve them • Patterns that actually get asked Because in interviews, it’s not about how much you know. It’s about how you think. If your interview is in the next few days, this will help you bring everything together. Link to the video in comments 👇

Most devs fail sliding window problems in interviews. Not because they don't know the algorithm. Because they can't explain why it works. Here's the mental model that changes everything: Brute force checks every substring from scratch → O(n³) Sliding window reuses what you already know → O(n) The key insight: when you hit a duplicate character, you don't restart. You just shrink from the left until the duplicate is gone. Two pointers. One set. Linear time. while s[right] in char_set: char_set.remove(s[left]) left += 1 That single loop is the entire trick. Each character is visited at most twice — once added, once removed. That's why it's O(n) despite the nested while. I've seen candidates code this correctly and still get rejected. Because when the interviewer asked "why is this linear?" they froze. Complexity analysis isn't a bonus point. It's the interview. Can you explain O(n) vs O(n²) to a 5-year-old? #TechInterviews #Python #Algorithms #SoftwareEngineering #CodingInterview

🚀 Last-minute interview prep? I found something actually useful. I was looking for quick revision content before interviews (without going into 10 different resources)… and came across this playlist by Ankit Bansal Honestly, it's precisely what most of us need at the last moment. It covers: 📊 SQL (real interview-focused) 🏗️ Data Warehousing & Modeling ⚡ Spark basics 🐍 Python concepts No unnecessary theory. No over-explaining. Just the kind of questions and concepts that actually come up in interviews. 💡 What stood out to me: → You can revise fast without feeling overwhelmed → Content is practical, not textbook-style → Good for connecting scattered concepts quickly Most of the time, we overprepare or keep jumping between resources. But before interviews, what really helps is: clarity + focused revision. This is one of those resources. If you’re in the same phase, it might help you too. Don’t aim to learn everything. Aim to revise what matters. #DataAnalytics #SQL #Python #DataEngineering #InterviewPrep #JobPreparation #CareerGrowth #Upskilling #DataAnalyst

One SQL mistake can change the entire interview. Not tools. Not experience. Just this: 👉 SQL 👉 Python 👉 How you think under pressure That’s what Data Engineering interviews really test. Mistakes in interviews are costly. Once you lose an opportunity, it may become someone else’s opportunity. Be prepared before you attend. Don’t attend interviews just to test your luck. We spend months chasing tools… But fundamentals are what actually decide the result. Are we preparing the right way? #DataEngineering #SQL #Python #InterviewPrep #TechCareers #Learning #CareerGrowth #Engineers #RealTalk

Coding interviews aren’t about solving random problems. They’re about recognizing patterns... .... If you focus on the right patterns, preparation becomes much easier. Here are some important ones to cover: 1. Sliding Window → Longest Substring with K Distinct Characters 2. Intervals → Merge Overlapping Intervals 3. Two Pointers → Container With Most Water 4. Subsets / Substrings → Maximum Subarray 5. Palindromes → Longest Palindromic Substring 6. Dynamic Programming (Decision Making) → Best Time to Buy and Sell Stock You don’t need to solve 100s of problems. Focus on understanding these patterns deeply, and you’ll be able to tackle a wide range of questions. Good luck with your upcoming Interview ❤️

A few months ago, one of my juniors called me late at night. He said, “I know Python. I’ve done SQL. I’ve watched so many tutorials… but I still don’t feel ready for interviews.” This is where most people get stuck. They are learning, but not in a way that prepares them for real interviews. The problem is not lack of effort. It’s lack of direction and structure. I’ve seen this pattern again and again. People keep switching resources, solving random questions, and consuming content… but don’t follow a clear roadmap. That’s where platforms like AccioJob come in. They focus on turning learning into real interview readiness, not just theory. Because at the end of the day, it’s not about “I know this” it’s about “I can crack this.” If you are curious to explore.

Hey #dev, still afraid of #codechallenge? Hmmm... maybe this will help you in #job #interviews, especially if it’s in #Rust. I saw a post by Ashish Pratap Singh on LinkedIn about top #leetcode problems you should study, and, since I had already written implementations in Rust for almost all of these types of problems, I decided to create this page with explanations and source code. I had to add two or three more, but it turned out really great for you, who are studying for job interviews. Coming next: #Golang, #python, and #typescript versions.
